  1. Overview of this Critical Patch Release
  ======================================================================
     This critical patch resolves the following issue:

     Issue:    When the VSAPI engine recognizes an email sample as a
               "HEUR_" or "EXPL_" virus file but the sample does not 
               trigger ATSE engine rules, ScanMail (for Microsoft
               Exchange) 11.0 Service Pack 1 does not send the sample 
               to Trend Micro Deep Discovery Analyzer for analysis and 
               performs actions locally instead.   
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution: This critical patch ensures that when the VSAPI engine 
               detects a "HEUR_" or "EXPL_" virus file that does not 
               trigger ATSE rules, ScanMail (for Microsoft 
               Exchange) 11.0 Service Pack 1 sends the file to Deep 
               Discovery Analyzer for further analysis.
